Abstract:

The corrosion rate of metals in natural seawater is a function of their metallurgical characteristics and of environmental factors such as temperature, velocity, and chemical makeup of the waters. It was observed that metal surface in natural waters became populated with periphytic bacteria in as little as a four-hour exposure time. Subsequent colonization by a variety of microorganisms produced a complex microfouling layer composed of periphytic microorganisms, their extracellular metabolites and cellular breakdown products, and metal corrosion products. This paper reviews some of the information available on biological corrosion, and discusses possible mechanisms involved. Author
